Question 1

Why did my plant die after I repotted it?

Accepted Answer

Almost always transplant shock, made worse by one of a small number of repotting mistakes. The plant did not die from being moved as such — it died because the root system could no longer supply the top growth.

Roots are fine, fragile and covered in tiny root hairs that do most of the actual water uptake. Teasing apart a rootball, shaking soil off or breaking roots destroys a large fraction of those hairs. The leaves carry on transpiring at their previous rate, and for days or weeks the plant is losing more water than it can take up. Wilting, leaf drop and browning edges follow.

The common aggravating mistakes are worth checking against what you did. Potting into a container far larger than the old one leaves a mass of wet, unrooted compost around a small rootball — it stays saturated, excludes air, and rots the roots. Going up one or two sizes is the rule. Burying the stem deeper than it sat before invites rot at the collar. Repotting a plant that is in flower or in active summer growth gives it no slack. Using garden soil instead of potting compost compacts in a pot and drains badly. And a pot without drainage holes will drown a plant no matter how carefully you water.

Recovery, when it happens, comes from reducing demand while the roots rebuild. Move the plant out of direct sun into bright indirect light, keep the compost evenly moist but never soggy, raise humidity, and remove some foliage to cut transpiration. Do not feed — fertiliser on damaged roots makes things worse. Autumn and early spring are the low-stress windows for repotting.

Question 2

Why does an overwatered plant look exactly like a thirsty one?

Accepted Answer

Because both end in the same place: the roots cannot take up water. The plant wilts for the same immediate reason in both cases, which is why the symptom is genuinely ambiguous and why so many

Question 3

Why are my plant's leaves turning yellow?

Accepted Answer

Yellowing is a general stress response rather than a specific diagnosis, so the pattern matters more than the colour. Which leaves yellow, and how, narrows the cause considerably. Overwatering is the

Question 4

What does pruning actually do to a plant?

Accepted Answer

It redirects growth rather than simply removing material — and understanding the mechanism is what turns pruning from guesswork into something predictable. The central principle: apical dominance.

Question 5

Why does supermarket basil die so quickly?

Accepted Answer

Because a supermarket basil pot is not one plant. It is dozens of seedlings sown densely into a small volume of compost, grown fast under glass, and intended to be harvested whole within a week or

Question 6

Why does a plant look worse at home than it did in the garden centre?

Accepted Answer

Because it was grown in conditions you cannot reproduce, and what you bought was a plant at an artificial peak rather than a plant in a stable state. What commercial growing does to a plant: Ideal

Question 7

Why do my houseplant leaves have brown crispy tips?

Accepted Answer

Brown, dry tips are a water-balance problem in the broadest sense: the leaf edges are the furthest point from the roots, so they are the first tissue to be sacrificed when water delivery falls short
